specifically, when the lifting convex portion 325c abuts against the bottom of the second pressing claw 322b, the second pressing claw 322b is lifted, and the bottom pressing structure 322 is in a relaxed state; when the lifting convex portion 325c is separated from the bottom of the second pressing claw 322b, the second pressing claw 322b is reset, and the bottom pressing structure 322 is in a pressing state. That is, the second pressing switch 325 controls the lifting/resetting state of the second pressing claw 322b, and thus controls the loosening/pressing state of the bottom pressing structure 322 on the workpiece 4 to be welded.
